Publish today \u00b7 reviewed 1 September 2026<\/p>\n\n\n\n

GitHub\u2019s 31 August 2026 changelog groups the Copilot changes shipped across VS Code versions 1.132 through 1.135 during August. The release cluster is less about one headline model and more about the way a team starts, reviews and continues agent sessions: side-by-side chats, searchable transcripts, portable plugins, provider switching, an integrated browser and on-device dictation.<\/p>\n\n\n\n

For a marketing or technical-content team, the practical question is not \u201cwhich button is newest?\u201d It is which parts reduce context switching while keeping code, copy and approvals reviewable. This summary sticks to GitHub\u2019s changelog and labels provider-dependent or experimental behavior.<\/p>\n\n\n\n

Agent sessions are easier to navigate<\/h2>\n\n\n\n

GitHub says Copilot in VS Code added side-by-side chats, a prompt timeline and tools for session details and diffs. The changelog also describes a \/btw side conversation that shares context and cache with the main conversation. Full transcript search, a sticky prompt and editor\/terminal improvements are aimed at the same friction: a useful answer is hard to reuse when it is buried in a long session.<\/p>\n\n\n\n

A simple team convention helps. Give each session a reader-job name, keep the acceptance criteria in the first prompt and record the final file or URL that changed. That is consistent with DMT\u2019s agent-harness guidance<\/a>: context is an operational resource, so make it inspectable rather than assuming an agent remembers everything.<\/p>\n\n\n\n

Plugins and model providers broaden the workflow<\/h2>\n\n\n\n

The August cluster highlights portable Agent Plugins 1.0. GitHub also says users can switch model providers, continue external sessions and connect windows to the same session. An Agents window can be used without GitHub sign-in when a Claude API key is supplied, according to the changelog.<\/p>\n\n\n\n

These are workflow options, not a guarantee that every provider exposes the same capabilities. Before a team standardises on a plugin or provider, test the exact model, authentication path, tool permission and data boundary. Keep the repository or content workspace as the source of truth. DMT\u2019s Work and Codex guide<\/a> offers a comparable permission-first approach for other AI workspaces.<\/p>\n\n\n\n

GitHub also labels an experimental \/rubber-duck command. Experimental means it belongs in a test path with a clear fallback, not in an undocumented production dependency.<\/p>\n\n\n\n

Review tools make the human checkpoint more visible<\/h2>\n\n\n\n

The release notes call out a hybrid Markdown diff editor, editor switching, terminal reflow and per-model token-usage details. These small changes matter when an agent touches a landing page, schema file or content repository. A diff can show what changed; token details can help a team understand why a session stopped or required a different model. Neither is a substitute for tests, a content review or a production read-back.<\/p>\n\n\n\n

Use a three-pass review:<\/p>\n\n\n\n

    \n
  1. Read the diff for scope: are only the requested files and sections affected?<\/li>\n
  2. Run the relevant tests or page checks.<\/li>\n
  3. Have a human confirm the copy, links, accessibility and business claim before release.<\/li>\n<\/ol>\n\n\n\n

    For SEO work, pair the code diff with DMT\u2019s technical SEO checklist<\/a> and content-audit process<\/a>. A green build does not prove that the page has the right search intent or canonical.<\/p>\n\n\n\n

    The integrated browser connects source and rendered page<\/h2>\n\n\n\n

    GitHub says the integrated browser can annotate HTML elements, automatically reload HTML files and open HTML in the browser by default. A developer or technical marketer can therefore inspect a rendered element, make a targeted source change and see the page reload without constantly switching applications.<\/p>\n\n\n\n

    Keep the browser loop bounded. Use test data, avoid entering credentials into an agent prompt, and treat the browser as a review surface unless a write action is explicitly approved. For a content team, the browser can help compare the intended page with the output; it does not establish that an external platform will rank or convert the page. DMT\u2019s search-intent guide<\/a> remains the decision layer.<\/p>\n\n\n\n

    Dictation is an input improvement, not an authority layer<\/h2>\n\n\n\n

    The changelog says dictation runs on device, supports multiple languages and can clean up shell commands with awareness of terminal context. That may make it easier to capture a prompt or explain a change while working. Read the transcript before sending it: names, paths, flags and numbers are precisely the details that a voice transcription can change.<\/p>\n\n\n\n

    For a team workflow, make dictation draft-only by default. Confirm the final prompt, inspect the diff and keep an audit note when the action affects a shared repository.<\/p>\n\n\n\n

    What to test first<\/h2>\n\n\n\n
